VIDEO: Bull Elk Produces Bloodcurdling Screech While Pursuing Mate

You do not want to be alone in the woods and hear this... A game cam in Montana captured the unsettling sound as a bull elk chased a herd of females through the wilderness. He begins to "bugle", which is a high-pitch call, as he passes the camera. The bloodcurdling noise is an expression of his intentions with the lady elk - if I were them I'd run too.
